| Abstract/Contents: | "Zoysiagrass is among the most economically important warm-season turfgrasses produced and managed by the green industry in Texas. This turfgrass is well-suited to residential and commercial use due to its aesthetic appeal, excellent heat and drought tolerance, and good shade and cold tolerance. Large patch caused by Rhizoctonia solani is a serious disease that occurs in the spring and the fall when zoysiagrass is exiting or entering dormancy. The disease weakens turfgrass and reduces its quality, and kills it in a severe infection. Control of large patch is of concern not only to homeowners, but also to sod producers and turfgrass managers in Texas, who encounter significant economic loss as a result of chemical inputs, lower market value and failure to harvest blighted sod. Despite the use of fungicides, control of large patch is difficult due to the biology of the causal agent. Once established in the soil, R. solani cannot be eliminated. Disease symptoms usually disappear and turfgrass recovers in the spring as the soil temperature increases. However, disease outbreaks tend to return and patches expand in the same location in the fall when environmental conditions are more favorable for disease development. Before efficient and effective management practices for large patch are developed, the causal agent needs to be properly identified, characterized and monitored. A toothpick baiting method has been developed to effectively isolate R. solani and to monitor pathogen activity year-round in zoysiagrass in southeast Texas. Since knowledge is lacking concerning environmental conditions favorable for large patch development, soil moisture was monitored and its relationship with pathogen activity was determined." |
